Human blood circulation includes arteries and veins. In arterial surgery, the heart plays the most important role; For veins, the pressure caused by muscle contraction is one of the hemodynamics, and the venous return of legs mainly depends on the contraction of calf muscles. Professor Liu Changxin said that taking care of the calf is equivalent to adding a "pump" to the lower part of the body, which can help the heart.

Legs are "communicating arteries"

50% of the nerves, blood vessels and blood in the human body are in the legs. There are more than 60 acupoints on the calf, and six important meridians, Foot Sanyang Meridian and Foot Yin San Meridian, also pass through the calf, which are important communication arteries of the human body and maintain the up-and-down movement of qi and blood.

Legs are "disease reflex zones"

Many diseases will be reflected in the calf. For example, calf cramps may be related to calcium deficiency, swelling indicates visceral diseases, and chills indicate weakness and fear of cold. Finding symptoms in time is beneficial to the early prevention and treatment of diseases.

Aging begins with the legs.

As the saying goes: the old roots of trees decay first, and the old legs of people rot first. When people get old, the accuracy and transmission speed of instructions between legs and brain decrease, which is not as tacit as when they were young. Experts explained that from birth to death, legs have been working. If you don't pay attention to protection, you will naturally fall into disrepair.

Hold one leg tightly in the palm of your hands, knead it and rotate it for about 20 times, and then knead the other leg in the same way. This method can strengthen the leg strength.
